The JBX43598 ST/APC to FC/APC simplex fiber patch cable represents a professional-grade connectivity solution for single-mode fiber optic networks. With an 85-meter length, this cable bridges equipment separated by significant distances while maintaining signal fidelity in telecommunications and data center environments. **Technical Excellence**: This singlemode fiber cable features a 9/125 micron core specification, the industry standard for long-distance signal transmission. The G.657.A1 glass fiber composition ensures superior performance, while measured attenuation of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm delivers efficiency across critical wavelengths. Insertion loss testing confirms ≤0.35dB typical performance, with return loss exceeding 20dB for optimal signal reflection characteristics. **Connector Compatibility**: The ST/APC to FC/APC configuration provides versatile compatibility with equipment from multiple vendors. APC (Angled Physical Contact) connectors minimize back-reflection, crucial for maintaining signal quality in sensitive applications like CWDM, DWDM, and precision instrumentation. **Installation Features**: The distinctive yellow jacket (1.8mm outside diameter) with OFNR riser rating suits indoor building installations and riser applications. The straight-through polarity configuration simplifies installation procedures and reduces configuration errors. **Compliance & Standards**: TAA compliance ensures this cable meets U.S. government procurement requirements. Manufacturing to ANSI/TIA/EIA-455-171-A standards guarantees quality construction and predictable performance. The cable carries a 90-day limited warranty and ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on qualifying orders. **Applications**: Ideal for telecommunications backbone networks, data center interconnects, telecommunications equipment rooms, fiber-to-the-premises installations, and any environment requiring robust 85-meter simplex single-mode connectivity. Custom lengths are available for non-standard requirements.
